Buckingham Palace confirmed Prince Harry had written a private letter of condolence to the family

Mrs Hunt, who herself is a Warrant Officer with 32 Engineer Regiment, revealed that the 39-year-old had struggled constantly being given a new doctor when he moved regiments, meaning he would have to start from scratch.

WO Hunt struggled with depression and mood swings, leading to the couple to divorce in 2014.

But Mrs Hunt said: "He wanted to protect us. We broke up but we never separated. He was still my best friend. I still loved him very much and I always will."

WO Hunt's father also blamed Government cuts, saying Nathan did not receive the help he needed on returning.

His body was found in his home city, Lincoln, at the start of this year, with the couple's daughter Megan telling mourners at her father's funeral "close together or far apart, my daddy will always be in my heart."
